Delta and Northwest link frequent flyer programs

Delta SkyMiles and Northwest WorldPerks members now have the ability to link frequent-flyer accounts and transfer miles between both accounts at no charge. Members who link their accounts before March 15 will earn 500 bonus miles. This new feature allows members who have SkyMiles and WorldPerks accounts to visit delta.com or nwa.com, link their accounts and transfer any amount of miles into either account on an unlimited basis. Both accounts will remain open and functioning until late 2009 when Delta plans to merge the two programs to deliver one best-in-class loyalty program for members in 2010.
